Tiger Lake is Intel's codename for the 11th generation Intel Core mobile processors based on the Willow Cove Core microarchitecture, manufactured using Intel's third-generation 10 nm process node known as 10SF ("10 nm SuperFin"). Tiger Lake replaces the Ice Lake family of mobile processors,[4] representing an optimization step in Intel's process–architecture–optimization model.

Tiger Lake processors launched on September 2, 2020, are part of the Tiger Lake-U family and include dual-core and quad-core 9 W (7–15 W) TDP and 15 W (12–28 W) TDP models.[5] They power 2020 "Project Athena" laptops.[6][7][8] The quad-core 96 EU die measures 13.6 × 10.7 mm (146.1 mm2), which is 19.2% wider than the 11.4 × 10.7 mm (122.5 mm2) quad-core 64 EU Ice Lake die. The 8-core 32 EU die used in Tiger Lake-H is around 190 mm2.[9] According to Yehuda Nissan and his team, the architecture is named after a lake across Puget Sound, Washington (state) from Seattle.[10] Laptops based on Tiger Lake started to sell in October 2020.[11]

The Tiger Lake-H35 processors were launched on January 11, 2021. These quad-core processors are designed for "ultraportable gaming" laptops with 28-35 W TDP.[12] Intel officially launched the 11th generation Intel Core-H series on May 11, 2021[13] and announced the 11th generation Intel Core Tiger Lake Refresh series (1195G7 and 1155G7) on May 30, 2021.[14]

Features

CPU

  • Intel Willow Cove CPU cores[15]
  • TAGE-like directional branch predictor (with a global history size of 194 taken branches)[16]
  • Indirect branch tracking and CET shadow stack[17]
  • Intel Key Locker[18][19]

GPU

IPU

  • Image Processing Unit, a special co-processor to improve image and video capture quality
  • Not available on embedded models
  • Initially there were 1165G7, 1135G7, 1125G4 and 1115G4 models with no IPU but later embedded processors were introduced instead

I/O

  • PCI Express 4.0[33] (Pentium and Celeron CPUs are limited to PCI Express 3.0)
  • Integrated Thunderbolt 4 (includes USB4)
  • LPDDR4X-4267 memory support
  • LPDDR5-5400 "architecture capability" (Intel expected Tiger Lake products with LPDDR5 to be available around Q1 2021 but never released them)[34][35][36]
  • Miniaturization of CPU and motherboard into an M.2 SSD-sized small circuit board[22]

Hardware telemetry

  • Add Intel Platform Monitoring Technology[37]

List of Tiger Lake CPUs

Mobile processors (Tiger Lake-H)

  • All models support DDR4-3200 memory
  • All models support 20 reconfigurable PCI Express 4.0 lanes, allowing x16 Gen 4 link for discrete GPU and x4 Gen 4 link for M.2 SSDs
